16 KByte Flash Module (S12FTMRG16K1V1)
The FPROT register, described in
accidental program or erase. Two separate memory regions, one growing downward from global address
0x3_FFFF in the Flash memory (called the higher region), and the remaining addresses in the Flash
memory, can be activated for protection. The Flash memory addresses covered by these protectable regions
are shown in the P-Flash memory map. The higher address region is mainly targeted to hold the boot loader
code since it covers the vector space. Default protection settings as well as security information that allows
the MCU to restrict access to the Flash module are stored in the Flash configuration field as described in
Table

0x3FF08-0x3_FF0F form a Flash phrase and must be programmed in a single command write sequence. Each byte in
the 0x3_FF08 - 0x3_FF0B reserved field should be programmed to 0xFF.
